How to Keep Heat Styling from Ruining Your Hair

Use heat protectant on damp hair, keep tools under 350°F, and limit styling to 2-3 times per week.

Most heat damage happens because people use too much heat too often, not because they chose the wrong product. Lower temperature and fewer sessions will do more for your hair than any expensive protectant.

1. Start with clean, towel-dried hair. Wash with a strengthening shampoo and apply a lightweight conditioner from mid-length to ends. Gently towel dry until hair is damp, not soaking. Heat protectant works best on slightly wet hair because it creates a more even barrier.
2. Apply heat protectant strategically. Spray or distribute product from roots to tips, focusing on the most fragile areas like ends and around your face. Use a wide-tooth comb to ensure even coverage. Don't skip this step even if you're in a rush.
3. Set your temperature correctly. Fine hair needs 250-300°F, medium hair 300-350°F, thick or coarse hair can handle up to 400°F. Most damage happens above 350°F, so err on the lower side. Your hair should sizzle very quietly, not steam or smoke.
4. Move tools quickly and smoothly. Don't clamp down and hold in one spot. Keep blow dryers moving constantly and flat irons gliding in single passes. If you need another pass, let the section cool for 10 seconds first.
